Prostatic Artery Embolization through the Profunda Femoris Artery

Abstract

An 88-year-old catheter-dependent patient with peripheral vascular disease and benign prostatic hyperplasia was referred for prostatic artery embolization (PAE). Selective angiography of the left internal iliac artery (IIA) revealed a 2.5-cm aneurysm and a single artery comprising the anterior division of the IIA (inferior gluteal artery). No prostatic artery (PA) was identified on the left. Additional angiography of the left external iliac artery (EIA), right IIA, and right EIA did not demonstrate prostatic perfusion. The right profunda femoris artery was then selected given previously reported atherosclerotic collaterals, which revealed an ascending branch of the medial circumflex femoral artery coursing through the upper thigh into the pelvis and reconstituting the right anterior division of the IIA. A 2.4-French microcatheter (Terumo) and 0.018-inch wire (Transcend, Boston Scientific) were used to enter the pelvic vasculature, right PA was identified, and a 2-mm coil was used to perform embolization of a potential nontarget anterior division branch. Embolization of the right PA was then performed with 250-µm particulate and Gelfoam slurry. Two-week follow-up revealed spontaneous voiding and catheter independence.
